G 21-0-G 24 德國(guó)哈威截止閥

德國(guó)哈威截止閥G 21-0-G 24 ：   哈威截止閥屬于強(qiáng)制性的密封式閥門(mén)，所以我們必須對(duì)截止閥閥瓣進(jìn)行施加壓力才能將哈威截止閥的閥門(mén)關(guān)閉。這樣對(duì)截止閥進(jìn)行強(qiáng)制性的加壓可以保證密封面不會(huì)出現(xiàn)泄露的問(wèn)題。而在當(dāng)油液經(jīng)過(guò)閥瓣進(jìn)入閥流的時(shí)，我們需要克服阻礙力來(lái)進(jìn)行操作，阻礙力主要是閥桿和填料之間的摩擦力和由介質(zhì)的壓力所產(chǎn)生的一種推力，因此在日常操作時(shí)我們往往會(huì)發(fā)現(xiàn)回避開(kāi)啟哈威截止閥所使用的力氣比關(guān)閉哈威截止閥所使用的力氣要小的多。因此關(guān)閉哈威截止閥采用了較大直徑的閥桿的設(shè)計(jì)理念，以保證閥桿不會(huì)因操作人員使用力量過(guò)大兒出現(xiàn)故障問(wèn)題。
